Best Cutting Tool Coolants Buying Guide
Before choosing the best cutting tool coolants you should consider following options:
1. Water-based cutting fluids: In the 1950s and 1960s, cutting fluids were oil-based. Today, water-based cutting fluids are the norm.
Water-based fluids contain a water-soluble oil, such as kerosene, as the base, along with a dispersant to keep the solids in suspension. Water-based fluids are less toxic than oil-based fluids, and they can be disposed of in the sewage system.
2. Solids suspension: The best cutting fluids contain a dispersant that suspends the solids in the fluid. Solids, such as aluminum oxide and silicon carbide, are used as an abrasive in the fluid to smooth and finish the edges of the metal being cut.
The addition of a suspending agent prevents the abrasives from settling out of the fluid and clogging the tool.
3. Corrosion protection: The proper fluid will protect the cutting tool and the workpiece from the corrosive effects of the water-soluble oil.
The fluid should contain inhibitors to protect against corrosion, along with inhibitors to protect the metal from the abrasive itself.
4. Fluid viscosity: The fluid should have the proper viscosity for the application. Fluid viscosity is determined by density, temperature and degree of suspension, among other factors.
For example, a low viscosity fluid will reduce friction and improve efficiency and heat removal, but will have a shorter life span. High viscosity fluids will have a longer life span, but will have higher friction and reduced heat removal.
The correct fluid viscosity depends on the application. Cutting aluminum on a flat surface with a straight-line blade requires a lower viscosity than cutting steel with a compound-curved blade on an uneven surface.
5. Environmental factors: The proper fluid will be selected based on the application. For example, a lower viscosity fluid will be needed when cutting in hot environments, because heat reduces the viscosity of the fluid.
In cold environments, a higher viscosity fluid may be needed because heat will cause the fluid to thin. The temperature of the surrounding environment must be considered when choosing the correct cutting fluid.
6. Maintenance: Cutting fluids will have a shorter life span if the machine is not maintained properly. For example, fluids will last longer if the abrasives are filtered out of the fluid and not introduced back into the machine for another cutting operation.
What else you should know about cutting tool coolants
1. What are the benefits of using a cutting tool coolant?
Some benefits of using a cutting tool coolant are that it can help extend the life of the tool, improve the surface finish of the workpiece, and increase the feed rate.
2. What are the different types of cutting tool coolants?
The four most common types of cutting tool coolants are oil-based coolants, water-based coolants, soluble oil coolants, and emulsion coolants.
3. How do you select the right cutting tool coolant for your application?
Cutting tool coolants are typically selected based on the type of material being cut and the desired finish.
4. How do you properly mix and apply cutting tool coolants?
Cutting tool coolants are typically mixed at a ratio of 5 parts coolant to 1 part water. The coolant should be applied to the cutting tool prior to use, and the tool should be kept lubricated throughout the cutting process.
5. What are the safety precautions you need to take when using cutting tool coolants?
Some safety precautions to take when using cutting tool coolants include: avoiding skin contact, wearing gloves and eye protection, and providing ventilation when using the coolant.
